experience during the service learning‚ and I also supposed it’s a valuable class for me because I learned a lot of things about pollution. The first part of The Recyclemania Service Learning was to talk about the environmental disruption‚ especially the water pollution and the disafforestation in the American West. The instructor showed how serious the water pollution was. Many factories and rubbish recycle companies dump their refuse into the rivers or oceans. The flotsams not only pollute

Classification of tropical‚ sub-tropical and acid zone fruit – area and production – scope and importance. Climate is of fundamental importance in the development of fruit cluster. Fruit has been a major food for mankind from time immemorial. Primitive man‚ the food habit was based mainly on fruits and also tubers which were found wild in the forests. In fact Adam who is considered to be the progenitor of man was said to have temptingly given the apple. In Ramanaya and Mahabaratha the cultivation

It contains various kinds of impurities such as dust particles‚ dissolved gases‚ dissolved minerals‚ microscopic paints and animals‚ suspended impurities and bacteria. These are natural impurities derived from the atmosphere‚ catchments area and soil. Besides this‚ there are various other reasons by which water i9 polluted. The upland surface water derives its impurities from the catchments area‚ the sources being human habitations and animal keeping or grazing. It is therefore very necessary

For example‚ in Queensland a deep‚ fertile clay soil is suitable for intensive agriculture but a shallow‚ sandy soil is better suited to grazing and growing native trees. The suitability of a soil for a particular purpose can often be

Soil‚ which is one of the most important natural resources‚ is often less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved.

Soil is the layer of broken rock particles and decaying organic matter on the surface of earth‚ which is essential for the growth of plants. It comprises of all the necessary nutrients that aid the growth and development of plants and trees. There are different types of soils‚ each one of them varying in its nature and texture. While some soils are deep rooted‚ the others are present on the margin. They also differentiate in their color‚ as some may be red while others are black. There are various

defined as soil. Soils come in an almost infinite variety of vertical structures and textures. Most soils are hundreds of years old and change very slowly. The work ability of the soil is the ease in which a soil can be cultivated and is determined by the soil texture. There are distinct layers of soil that are not always visible to eye but are made up of different horizons. O horizon/Humus is the decomposing plant matter. A Horizon/Topsoil is the mixed humus and leached mineral soil. E Horizon/

Soil texture is related to a number of important soil characteristics such as water holding capacity‚ soil drainage‚ and soil fertility. In order to make this lab work to our own convenience we will use soil from our nearby area. This project was conducted to specify what type of soil there is in the area and what it can be used for.

INTRODUCTION Soil is the precious gift of nature to the mankind. All the plant family‚ animal kingdom and human society at large depend upon soil for their sustenance directly or indirectly. Ironically‚ soil is the most neglected commodity on the earth. Shifting cultivation on the hill slopes‚ non-adoption of soil conservation techniques‚ and over exploitation of land for crop production due to population stress‚ leads to enormous soil erosion. It will take hundreds of years to form an inch of soil‚ but
